OIL-CAN.

SPECIFICATIONforming part of Letters Patent No. 538,174, dated April 23,1895. Application tiled December 8, 1892. Serial No. 454,512. (Nomodel.)

To all whom, it may concern,.- Y

. Be it known that I, FREDRlOK JOHN MA- ROLF, a citizen of the UnitedStates, residing at Rock Rapids, in the county of Lyon, State of Iowa,have invented certain new and useful Improvements in Oil-Cans; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use ythe same.

My invention relates to oil cans in which the spout is provided with aplunger by means of which clogging is prevented and the spout keptopened thereby insuring a free supply of oil at all times.

The object of the invention is to utilize the spring bottom of the canas a means for operating the plunger and interposing between said springbottom and the plunger a lever or system of levers whereby said plungerwill have a movement of large amplitude from a slight movement of thespring bottom, thereby insuring the spout being kept clear ofobstruction.

The improvement consists of the novel features and the peculiarconstruction and combination of the partswhich will be hereinafter morefully described and claimed and which are shown in the annexed drawings,in which- Figure l is a perspective view of an oil can embodying myinvention, parts being broken away to show the lever and the connectionsbetween said lever and the plunger and bottom of the oil can. Fig. 2 isaview similar to Fig. 1 showing a modification which consists of aseries of levers and connections between said levers and spring bottomand plunger.

The oil can A having the spout B and the spring bottom C may be of anydesired construction. The lever D extending parallel with the bottom C,is supported near one end on a cross bar E which is secured at its endsto the sides of the oil can. The short arm of lever D is connected withthe spring bottom O by a rod F and the long arm is connected directlywith the plunger G. In order that the rod F may have connection with thespring bottom O at acentral point where the amplitude of vibration ormovement is greater the said rod is curved between its endssubstantially as shown. The inner end of the plunger G is similarlycurved to the rod F to connect with the longer arm of the lever D asshown. By reason of the spring bottom having connection with the shortarm of the lever D and the plunger having connection with the longer arma very slight movement of the spring bottom will produce an appreciablemovement of the plunger sufficient to keep the mouth piece open and freefrom obstruction.

In some cases it may be advantageous to reinforce the spring bottom Oand have the rod F attached directly to said reinforcement. Fig. 2 showsa construction in which a spring C is provided and lies close againstthe spring bottom O, the rod F being attached directly to said spring C.For all practical purposes the spring O and the'spring bottom C will beconsidered as a single element and will be comprised in the term springbottom.

In Fig. 2 a second lever H parallel with the lever D is provided andmounted on a cross bar I which is attached at its end to the sides ofthe oil can. The short arm of the lever H is connected with the long armof leverD by the rod 'L' and the plunger G is connected to the longerarm of said lever H. By this construction the plunger G receives agreater movement than from the construction shown in Fig. l, the springbottom receiving a like motion in each case. f

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In an oil can having a spring bottom, the combination of the levers Hand D parallel with each other and with the said bottom, and mountednear one end, a rod connecting the short arm of lever H with the longarm of lever D, a rod connecting the short arm of lever D with thecentral portion of the spring bottom, and` a plunger having connectionwith the long arm of the lever H, substantially as shown for the purposedescribed.

In testimony whereof I affix my signature in presenceof two witnesses.
